Description

Flexible carrying gripper

Technical Field

The utility model relates to the technical field of flexible production lines of vehicle bodies, in particular to a flexible carrying gripper.

Background

And at a welding station of the upper part of the threshold inner plate of the body-in-white flexible main line, the upper part and the positioning of the threshold inner plate are realized through threshold inner plate grippers, the threshold inner plate grippers grasp the threshold inner plate from a material frame or a centering table and carry the threshold inner plate to a specified position on the body-in-white through a robot, so that the positioning of the threshold inner plate is finished. In the welding process, the robot breaks away from the gripper, the gripper is placed on the clamp positioning mechanism, and the gripper is positioned by the clamp positioning mechanism. When the vehicle type is switched, different grippers are required to be switched according to different vehicle types.

Problems of the prior art

1) The inner plates of the doorsill of different vehicle types are positioned and carried by special grippers due to different positioning and molded surfaces;

2) Because the body structures are different, the positions of the white bodies on the main line can be different, and a clamp positioning mechanism for positioning the grippers can occupy a welding space to influence the welding efficiency;

3) In the process of vehicle type switching, a large number of sites are needed for storing the switched grippers.

Disclosure of Invention

In order to solve the technical problems, the utility model provides the flexible carrying gripper which can adapt to parts with different molded surfaces and has good flexibility.

In order to achieve the aim of the utility model, the flexible carrying gripper comprises a gun changing disc, an X-axis sliding mechanism, a Y-axis sliding mechanism, a first sucker, a second sucker, an octagon tube and a mounting seat, wherein the mounting seat is arranged on the gun changing disc, the X-axis sliding mechanism and the octagon tube are fixedly arranged on the mounting seat, the Y-axis sliding mechanism is arranged on the X-axis sliding mechanism, the first sucker is arranged on the Y-axis sliding mechanism, one end of the octagon tube is fixed on the mounting seat, and the second sucker is arranged at the other end of the octagon tube.

Further, the X-axis sliding mechanism comprises a Y-axis sliding mechanism mounting seat, a first servo motor and a first linear module, wherein the Y-axis sliding mechanism mounting seat is slidably mounted on the first linear module, and the first servo motor is connected with the first linear module.

Further, the Y-axis sliding mechanism comprises a first sponge sucker mounting seat, a second servo motor and a second linear module, wherein the first sponge sucker mounting seat is slidably mounted on the second linear module, and the second servo motor is connected with the second linear module.

Further, the first sucker and the second sucker are one of a sponge sucker, a vacuum sucker, a magnetic cylinder and a pointing cylinder.

The beneficial effects of the utility model are that

1) The flexible carrying gripper is developed, the position change of the sucker is realized by adopting a servo motor and a linear module, and the positioning accuracy is high;

2) The sponge sucker is used for sucking the parts, so that the sponge sucker can adapt to parts with different molded surfaces, and has good flexibility;

3) The flexible carrying gripper is simple in mechanism, and the sponge sucker can be replaced by a vacuum sucker, a magnetic cylinder, a pointing cylinder and other elements according to the unused use environment and positioning requirements.

4) The utility model adopts the octagonal tube and the linear module, has simple structure, convenient processing and manufacturing, light weight and good flexibility.
